2008-11-12 Tor Lillqvist <tml@novell.com> Bug 556415 - Crash on Windows 2000 in g_winhttp_vfs_init() * win32/gwinhttpvfs.h: Move the set of function pointers to winhttp.dll into a separate struct GWinHttpDllFuncs. Just have a pointer to that in the GWinHttpVfsClass. * win32/gwinhttpvfs.c: Move the lookup of functions from winhttp.dll into a function of its own, that stores the pointers in a separate GWinHttpDllFuncs variable. Add two bookeeping booleans lookup_done and funcs_found. Don't call g_io_extension_point_implement() to register the winhttp extension unless winhttp.dll has been successfully loaded and the required functions found in it. * win32/gwinhttp*.c: Adjust calls of the functions looked up from winhttp.dll correspondingly. svn path=/trunk/; revision=7648
